Magnetic Maps: Finding Hidden Metal with Magnetometers

A technical guide to using magnetometers for treasure hunting: understanding magnetic field principles, operating handheld units, marine magnetometry, analyzing magnetic field data to identify buried metal objects, and integrating magnetometry with other detection technologies. Covers notable discoveries made with magnetic survey methods.

Magnetometers detect iron and steel at depths no metal detector can reach—shipwrecks, buried caches, cannons, and even submerged structures. This book teaches the theory and practice of magnetic surveying, from equipment selection through data interpretation, unlocking targets buried too deep for conventional search methods.
